Magnetic Pick-Up Assembly

The pick-up coil assembly is located in the distributor. The start pick-up coil supplies a signal to the computer, which causes the spark plugs to fire at a fixed amount of advance during cranking only. Once the engine begins to run, the run pick-up coil takes over, supplying advance information to the computer.

The computer then modifies spark advance based on information from remaining sensors. The start pick-up coil can be identified by its 2-prong male connector. The run pick-up coil can be identified by its connector having one male prong and one female prong.
